MOL-D FOR CONCRETE POSTS.

SPECIFICATION forming part of Letters Patent No. 742,166, dated October 27, 1903.

Application filed August 30, 1902.

To all whom it may concern:

Be it known that I, HENRY H. OLOUGH, of Elyria, Ohio, have invented certain new and useful Improvements in Molds for Concrete Posts and the Like, of which the following is a specification.

In the manufacture of posts from cement, concrete, or other plastic material it is sometimes desirable to imprint upon one or more of the lateral faces of the posts the letters and figures corresponding to some legend or sign which it is desired the post shall bear. This is most conveniently done by molding the desired letters and figures directlyinto the concrete of which the post is composed; but inasmuchas the presence of the desired letterforms in the sides of the mold would tend to -prevent the post from being removed from To this end the invention consists in im-v provements herein set forth, and particularly pointed outin the appended claims, and will be fully understood from the following description of the construction illustrated in the accompanying drawings, in which- Figure 1 is an end elevationof myimproved mold for cement concrete posts. Fig. 2 is a top plan View thereof. Fig. 3 is a side elevation thereof. Fig. 4 is a transverse section taken on line 4 4 of Fig. 2. Fig. 5 is a side elevation of one of the removable sections to which the letter-forms are applied and showing several of the letter-formsin place thereon. Fig. 6 is an elevation of the inner face of this section. Fig. 7 is a top plan section taken on line 7 7, Fig. 5. Fig. 8 is a top plan detail of one of the letter-forms, showing the dovetailed construction by which itis detachably secured to the removable section. Fig.

9 is a perspective View of a railway mile-post, such as may be cast in my improved mold.

Serial No. 121,654. (No model- Fig. lOis a perspective detailofa blank spaceblock.

In said drawings, 1 designates myimproved mold as a whole, the same consisting of a bottom or base board 2, longitudinal top strips 3, end boards 4, which are rigidly secured to the ends of the bottom board and top strips, and a lining 5, extending from one of the top strips 3 down to the base-board and back to the other top strip, so as to form thesidesot' the mold. In the particular construction here illustrated the post is designed to be of substantially V shape in cross-section, and the two sides of the lining 5, which are preferably of metal, are consequently made to converge from each top strip 3 toward the base-board, where they meet in an apex which is almost a sharp edge. This converging'arrangement is desirable for the reason that it facilitates removal of'the post without the use of a plunger and without making the main parts of the mold separable, it being simply necessary in order to remove a post to invert the mold and jar or shake it. It will, however, be understood that this triangular form of post, while desirable and important in many respects, may be widely varied with-' out any essential alteration in the construc, tion of the mold so far as the present invention is concerned. Lateral ribs 6, inserted at intervals between the top strips 3 and the bottom or base board 2, serve to strengthen the mold and support the lining 5 against any pressure exerted on the concrete within it during the molding operation.

At the points where it is desired to provide the lettering on the posts the lining 5 of the mold is cut away on each side to form apertures 7, into which are thrust removable sections 8, Figs. 5, 6, and 7, the shape of which is such that when thrust into place in the mold the inner face of each section will be substantially continuous with the'inner face of the mold on that side. A dovetailed strip 9 is provided on such inner face of each section, and letter forms 10, Fig. 8, are so shaped as to slip over the dovetailed strip 9 and be held in place thereby with the letters projecting into the mold. To hold the sec= tions 8 removably in place, wide ribs 11 are provided at each side of and between the section-receiving apertures 7, and to the outer faces of these ribs are secured strips 12, which are made somewhat wider than the ribs, as shown in Fig. 2. Then after the sections are inserted between the ribs and into the apertures 7 of the lining wedges 13 are thrust down between the ribs 11 and behind the projecting edges of the strips 12, with their inner faces engaging the outer faces of the sections 8, thus locking the latter in position as though a permanent part of the mold. In order that the sections 8 shall be stopped with their in ner faces exactly in aline ment with the inner sides of the mold, their upper and lower ends are shouldered, as at 15, and these shoulders are arranged to abut against corresponding shoulders on the-frame of the mold.

With the construction thus described any legend or sign may be molded into the face of the post by simply slipping the desired letters and figures of the alphabet upon the sections 8 and wedging these latter into the apertures 7 of the mold at the desired points. Then when the mold is filled with concrete the letters thus inserted will impress themselves into the body of the post and form in sunken letters the wording and figuring desired thereon. After the post is hardened the sections 8 maybe withdrawn by firstpulling out the wedges 13, and the post is then free to be removed from the mold. If no lettering is desired at any aperture 7, the section 8 corresponding thereto may be filled out on its inner face by a blank 14:, so as to maintain the inner surface of the mold smooth and continuous at that point, and similar blank strips cut to any required length may be used to fill out the line of lettering at the top and bottom of each section 8 or inserted as space-blocks between any two words or characters.

A completed cement post such as may be cast in my improved mold is shown by way of example in Fig. 9. Only one lettered face of this post appears in this illustration; but it will be understood that the opposite face is similarly lettered to form the legend or sign appropriate to the direction from which the post is approached.

I claim as my invention 1. A mold for concrete posts provided with apertured side walls, letter-bearing sections removably inserted to said side walls through the apertured walls, ribs at the sides of and between the apertures, strips secured to and made wider than ribs and wedges entering between the sections and strips to lock the sections in place, substantially as described.

2. A mold for concrete posts consisting of an open trough having apertures in its side walls below its open top, letter-bearing sections reinovably inserted in said openings, means for restricting the inward movement of said sections, and wedge devices for removably locking said sections in place.

In testimony that I claim the foregoing as my invention I affix my signature,in presence of two subscribing witnesses, this 27th day of August, A. D. 1902.
